In 2016, an estimated 1,685,210 new cases of cancer will be diagnosed in the United States and 595,690 people will die from the disease. Although a few patients diagnosed with cancer can attribute their illness to a hereditary abnormal gene, most people believe their cancer was a result of a DNA mutation possibly caused by a handful of external factors such as environmental radiation, toxins, and poor diet. However, this may not be the case, as some bouts of cancer may be linked to the manner in which cancer cells produce energy.
